BOWLING-ALLEY ATTACHMENT.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed December 21, 1906. Serial No. 348,956.

To all whom, it may concern:

Be it known that 1, WILLIAM ROBERT AN- DREWS BALL, a citizen of the United States, residing at St. Thomas, in the county of Pembina and State of North Dakota, have invented a new and useful Bowling-Alley Attachment, of which the following is a specifi cation.

This invention has relation to attachments for bowling-alleys and it consists in the novel construction and arrangement of its parts, as hereinafter shown and described.

The object of the invention is to provide an attachment adapted to be applied to the end of a bowling-alley and which consists of a plate having front and rear sections which are disposed at an angle to each other. The rear section is i'mperforate, while the front section is provided with a series of openings having rearwardly inclined longitudinal edges. The said openings differ in size, and the partitions between the openings are provided with score characters to Which the player is entitled by passing a ball through a particular opening. The attachment is located directly over the pit of the alley, and such balls as do not pass through the said openings pass up the partitions between the openings and fall in the pit, while those balls that fall in the openings strike the rear portion of the attachment and are deflected down into the pit.

III the accompanying drawings, Figure 1 is a perspective view of the end of an alley with the attachment applied thereto. Fig. 2 is a vertical sectional view of the attachment and a portion of the alley, and Fig. 3 is a horizontal sectional view of a portion of the front sec tion of the attachment.

The attachment comprises a metallic plate 1, having a rear imperforate section 2 and a front section 3, provided with a series of openings 4. The said openings 4 differ in size, and the partitions 5, which separate the openings, have their longitudinal edges rearwardly inclined in order that precipitous surfaces may not be presented to the balls, consequently avoiding damage from this 'source.

Each of the partitions 5 is provided with a score character. Said characters differ according to the size of the adjacent openings, the characters of the least denomination being placed adjacent the openings of greatest area, and vice versa. The rear section 2 is disposed at an angle to the front section 3, and at the lower edge of the front section 3 is a strip 6, which is attached to the rear end and vertical sides of the alley 7 by screws or other securing device. Consequently when the balls are passed down the alley they either pass through the openings 4 and strike the rear section 2 and are deflected into the pit or run up the partitions 5 over the attachment and fall into the pit. When the balls take the latter course, no score counts.

By using such an attachment upon an alley the players become practiced and learn to deliver the balls with great accuracy. Also the attachment affords amusement, as the variance of score lends interest to the contest'.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An alley attachment comprising a plate having a rear imperforate section and a front section provided with openings, said sections being pitched at an angle to each other, said front section having at its lower edge a strip for attachment to the alley.

2. An alley attachment comprising a plate having a rear imperforate section and a front section provided with openings, said sec tions being pitched at an angle to each other, the partitions between said openings having their longitudinal edges rearwardly inclined, said front section having at its lower edge a strip for attachment to the alley.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
